Load the fictional example in a cleared form. Check the options, run the tool if needed, and compare the result below.
Calculate a SHA-512 digest from text encoded as UTF-8. Compare digests only when the exact text bytes and algorithm match; the fixed-length result cannot be decrypted. Enter text to calculate its SHA-512 digest with the browser Web Crypto API. A digest can help compare data, but it cannot be decrypted and is not a password-hashing scheme. A digest is not encryption and does not prove who created the input. Do not use a fast general-purpose hash by itself for password storage.

Quick answer
Calculate a SHA-512 digest from text encoded as UTF-8. Compare digests only when the exact text bytes and algorithm match; the fixed-length result cannot be decrypted.
The page and its assets load from the site; this operation uses your entered values only in this browser and does not send them to a calculation endpoint.
How to use it
Enter text to calculate its SHA-512 digest with the browser Web Crypto API. A digest can help compare data, but it cannot be decrypted and is not a password-hashing scheme.
Limits
A digest is not encryption and does not prove who created the input. Do not use a fast general-purpose hash by itself for password storage.
Frequently asked questions
Why does my digest differ from another tool?
Both tools must hash the same bytes with SHA-512. This page encodes the text as UTF-8 and includes every space and line break; it does not normalize the text first.
What is different about SHA-512?
SHA-512 is a member of the SHA-2 family and produces a 512-bit digest. Use the algorithm expected by the system you need to interoperate with.
Is SHA-512 encryption?
No. It is a one-way digest function; there is no decryption step.
Can I use it for password storage?
Do not use a fast general-purpose hash alone to store passwords. Use a dedicated password-hashing scheme.
